7 Claims. (Cl. 20-53) This invention relates to a window having apivoted sash and particularly to that type of window which has a sashpivoted on a vertical axis midway between the stiles.

In windows of this type the sash is so mounted and so constructed thatis capable of being rotated about its pivots to come to rest in theframe after a rotation of either approximately 180 or 360.

Obviously a push from the interior of. the room on either side of thepivotal axis of a sash of this type will cause the sash to open and thisability makes it possible to rotate the sash 180 so that both ofV itsfaces may be cleaned without the cleaner leaving the room or extendinghimself from the Window opening. It is also possible completely torotate the sash so that either face may be used on the outside of thebuilding.

Since, in a window of this type, the space between the frame and thesash must be heavily weather stripped, it is at times desirable toreverse the position of the sash by rotating the same 180 to adapt theweather stripping to a tighter fit during use.

In a window of this pivotal type and especially in windows having largesashes, it is necessary that the sash be securely locked and incapableof accidental unlocking to obviate the possibility of a personunintentionally opening the sash as for instance by leaning lagainst iton one side of the pivotal axis.

lt is an object of the present invention to provide a window having sucha sash as set forth above and wherein locking devices are provided whichare incapable of accidental unlocking and opening and which are renderedinoperative to lock the sash by sequential manual operations.

More specifically, it is an object of the invention to provide such awindow wherein, when the sash is swung closed from an open position, itautomatically will be ,locked at both window frame jarnbs and when it isdesired to open the sash an act of unlocking the automatic lock will atthe same time bring into operation a secondary locking device which,while it will permit the sash to swing slightly on its pivots toward acompletely open position, will prevent its swinging only to such anextent that it will be impossible for one operating the window to fallfrom the window opening.

With these and other objects in view the invention comprises thecombination and arrangement of parts illustrated in the drawings,described in the specification and recited in the claims.

In the drawings which disclose the preferred embodiment of theinvention,

Figure l is an elevational view of the inside of a window constructed inaccordance with my invention;

Figure 2 is a horizontal sectional view on line 2-*2 of Figure l,looking in the direction of the arrows;

Figure 3 is an enlarged fragmentary horizontal sectional view on line3--3 of Figure l looking in the direction of the arrows;

Figure 4 is a vertical sectional View taken in the plane a. c 2,812,557Ice Patented Nov. 12, 1957 of line 4 4 of Figure 3 looking in thedirection of the arrows;

Figure 5 is a perspective View of the latch operating cam, itssupporting barrel and operating key member, the same being shown inposition vertically reversed from the positions shown in full lines inFigure 4 in order more clearly to show the constructions;

Figure 6 is a fragmentary perspective view showing the construction ofand the relation of the strike plate to the window frame jamb.

The invention comprises a sash which is mounted in the frame of thewindow', as described in the forepart of this specification, and, asdisclosed in the drawing, in combination with an automatic lockingarrangement at each jamb of the frame which comes into operationautomatically as the sash reaches a closed position and which, whenrendered inoperative to lock the sash, will permit it to rotate aboutits vertical pivotal axis and in combination with a manually operabledevice for rendering the automatic locking arrangement inoperative andfor performing the additional function of preventing the sash fromswinging outwardly except to a limited extent until a deliberate manualsash releasing operation has been accomplished.

In thel drawings a window frame having a header 1, a sill 2 and jambs 3is disclosed. ln this frame a sash, having upper and lower rails 5 and 6and stiles 7 and is mounted to rotate horizontally on vertical pivots 9and 10 which are carried by the header 1 and sill 2 and have bearings inthe upper and lower rails 5 and 6 of the sash. The sash is sufficientlysmaller in dimensions than the window opening of the frame to permit itto be rotated 360 and the spaces between the sash and the frame areweather sealed by weather sealing members 11 which are carried by thesash and are preferably of the resilient and compressible type and ofsuch material as neoprene or the like. Each edge of the sash carries,preferably, a pair of spaced weather sealing members so that, regardlessof whether or not the sash is in one position or has been rotated tooccupy a position 360 from the original, the space between the sash andthe frame will be ,sealed at the outside as well as the inside of theWindow with the result that the weather sealing members not only deterthe ingress of the weather into the room but also protect the operatingparts of the window locking mechanisms.

In order that the sash may be locked automatically when it is swung to aclosed position and will positively lock the sash in such position, Ihave provided the following mechanism: each sash stile is provided witha spring projected latchabolt which is adapted, when the sash is closed,to project into an opening in a strike plate carried by the adjacentjamb of the frame when the sash is moved in a horizontal direction. Thislatch-bolt 12 is mounted for longitudinal horizontal movement within ahousing which is carried by the vertical stile of the sash and isnormally moved outwardly by a spring 14 which is located within thehousing and projects into a bore 15 in the latch-bolt 12, being normallyunder suicient compression to move the end of the latch-bolt out wardlyfrom the sash stile.

This outward movement of the latch-bolt is limited by engagement of ashoulder 16 on the bolt with a complemental shoulder 17 on a guide 18which is secured to the stile by suitable means such as bolts 19. It isto be noted that this guide has an extended portion 20 which tends tostrengthen the bolt and prevent its displacement when undue force isapplied to the sash.

The adjacent iamb is provided with a strike plate 21 which extendsacross the face of the jamb and is provided with divergent cam surfaces22 at its edges. This strike plate is secured to the adjacent jamb bysuitable fasteners 23 which engage ears 24 on the strike plate thatextend through a channel in the face of the jamb.

This strike plate is provided with an opening 26 which is adapted toreceive the end of the latch-bolt 12 when the sash is closed toeffectuate the locking of the sash in its closed position.

Thus, when the sash is open, the ends of the latch-bolts 12 will projectto their greatest extent from the stiles of the sash and whenthe sash ismoved to a closed position the ends of the `bolts will engage the camfaces 22 of the strike plates with the result that the latchbolts willbe moved inwardly against the action of the springs 14 until they alignwith the openings 26 at which time the springs automatically willproject the latchbolts into the openings and thus lock the sash.

In order that the latch-bolts 12 may be moved into` the sash stilesagainst the action of the springs 14 and out of the openings 26 to thusunlock the sash and permit it to be moved as desired about its pivotalaxis, I have provided the following mechanism: a cam 27 which is rigidwith and preferably integral with a barrel 28 is mounted within achamber 29 formed in the jamb by the strike plate 21 and the ears 24. Onone end of the barrel 28 is a bearing member 30 which pivots into and iscapable of rotating in a bearing 31 in a plate 32 which is secured tothe jamb by the bolts 23, as illustrated in Figure 6 of the drawing. Acomplemental bearing 33 is provided in the inside flange of the jamb andreceives a bearing member 34 on the barrel 28. This cam 27, wheninoperative, is in the position disclosed in Figure 4 of the drawing insolid lines but it may be rotated on the bearing members and 34downwardly into the dotted line position shown in this figure. As it isthus rotated, it engages the end of the adjacent latch-bolt 12 and movesthe same outwardly beyond the opening 26 in the strike plate 21 againstthe action of the spring 14. As will, be seen, in Figures 3, 4 and 5,the horizontal dimensions of this cam 27 (Figures 3, 4 and 5) are suchthat when the cam is rotated into the dotted line position shown inFigure 4 and extends into the opening 26 it will substantially closesaid opening, horizontally at least, to such an extent that thelatch-bolt, as the sash is rotated, will be excluded from entry into theopening and the sash may thus freely be moved toward an open position.

In order that these cams on the opposite sides of the window maymanually be operated to move the latchbolts against the actions of thesprings 14 and to subsequently withdraw from the openings 26, I haveprovided combined cam operating and sash retaining members, one for eachcam when used with a sash which is capable of 360 rotation. Each ofthese members 35 comprises a shank 36, a key portion 37 and a sashengaging member 38 which is preferably of rubber, neoprene or somesimilar material. The key portion of each member is adapted to enter theopening 39 and the slot 40 of one of the barrels 28 and to be limited inthe extent of its entry by the bearingy member 30. When the key portionis thus engaged and the cam 27 is in its inoperative position, the shank36 and the sash engaging `member 38 are located within the room adjacentthe face of the inner flange of the jamb with the shank 36, the sashengaging member 38 and the key 37 extending upwardly.

When it is desired to open the window the shanks 36 and the sashengaging members 38 of the cam operating and sash retaining members 35are rotated from the full line position shown in Figure l and the dottedline position shown in Figure 2 to extend toward each othersubstantially in horizontal positions as shown in dotted lines in Figurel and in full lines in Figure 2. When these members are rotated intothese horizontal positions, the camy 27 will be moved downwardly intothe dotted line positions shown in Figure 4 of the drawing and any suchmovement will force the latch-bolts 12 out of the openings 26 lin thestrike plates 21. The movement of the cam member 27 from the full lineto the dotted line position shown in Figure 4 is limited by theengagement of the abutment 27' with the window frame. The members 35,when released from manual control, will be retained in their horizontalpositions as a result of the pressure of the springs 14 exerted throughthe latch-bolts upon the barrels 28 in line with the axes of saidbarrels.

When the latch-bolts have been forced from the openings 26 in the strikeplates 21 `the sash is released for movement and may be partiallyrotated on the pivots 9 and 10 to the positions shown in full lines anddotted lines in Figure 2 by the exertion of a manual force on one sideof the sash pivot. However, the extent of this movement is only such asto move the latch-bolts out of alignment with the openings 26 in thestrike plates as, at this time, the stile at one side of the sash willengage the sash engaging member 33 on the shank 36 on the opposite sideof the pivot of the sash.

In order that the window sash may be rotated through substantially orsubstantially 360 it is necessary for the operator to remove the sashengaging member 38 which is at that time engaged by the stile out of thepath of movement of the sash. When thus removed from the path ofmovement of the sash, the sash engaging member 38 will permit the sashto be pivotally moved substantially 180 on its pivots but before it canbe moved 360, the other of the two sash engaging members 3S must bemanually moved out of the path of travel of the sash.

When the two members` 38 have thus been moved out of the path of travelof the sash, they will again extend upwardly and the cams 27 will berestored to their inoperative positions, extending upwardly asillustrated in full lines in Figure 4 of the drawing.

With the members 38 in their upwardly extending positions out of thepath of movement of the sash, the latchbolts 12 automatically willengage in the openings 26 of the strike plates 21 under the action ofthe springs 14 when the sash moves into the plane of the window frameand the bolts align with the openings.

Thus it'will be seen, that, even after the latch-bolts have beendisengaged from the strike plates, it will be impossible to swing thesash on its pivots suiiiciently to permit a person accidentally to fallfrom the window opening. To complete the release of the sash, the sasharresting members 38 mustmanually be moved out of the path of travel ofthe sash, and, when the sash is of considerable width, it is necessaryfor the operator to rst move one of the members 38 and to then move tothe other side of the window to move the other of the two members 38.

This sequential unlocking of the window greatly minimizes the chance ofa person falling from the windev.l opening by leaning against one sideof the sash.

It will be noted that the bearing opening 33 is of keyhole form, beingprovided with a downwardly extending slot 33' (Figure 6) to permit thekey portion 37 of the key member 35 to pass therethrough when the latteris withdrawn from the window frame. This key portion 37 aligns with thisslot 33 only when the cam Z7 is in the inoperative upwardly extendingposition shown in Figure 4 in full lines, at which time the bolts 12will lock the sash in closed position. This insures the key memberagainst withdrawal when the bolts 12 are in unlocking positions and thesash is free to move on its pivots.
